Problem 2
In the land of Skyrim, two-thirds of city guards were previously adventurers, but were forced to change professions after sustaining career-ending arrow-related knee injuries. Consider K to be a random variable representing the number of knee-injured guards working in a city that has 25 guards employed in total. Evaluate the following probabilities:
a) P(K = 16)
b) P(K = 17)
c) P(5 <= K < 11)
d) P(K = 0)
e) P(K = 25)
f) P(3 < K)

To compare two kinds of bumper guards, six of each kind were mounted on a car. Then the car was run into a concrete wall. Statistics for the costs of repairs are: ¯x1 = 140, ¯x2 = 149, (s1)^2 = 80, (s2) ^2 = 82. Assume that the two populations are normal, independent and have the same variance. Test at α = .01 the null hypothesis that there is no difference between costs of repairs.

Consider a city with three consumers: 1, 2, and 3. The city provides park land for the enjoyment of its residents. Parks are a public good, and the amount of park land (which is measured in acres) is denoted by z. The demands for park land for the three consumers are as follows: D1 =40–z, D2 =30–z, D3 =20–z. These formulas give the height of each consumer’s demand curve at a given level of z. Note that each demand curve...

WATER IS THE LIFEBLOOD OF THE EARTH, but by 2025, according to the U.N., two-thirds of the world’s population could face chronic shortages of water. In fact, some countries are already importing huge supertankers of freshwater from other countries. But one place that’s definitely not short of water is the state of Michigan, which has 11,000 lakes and is surrounded by Lakes Michigan, Huron, Superior, and Erie. So it came as a surprise to some that the Nestlé company’s new...
